Boneyard Acquaintance Feat 17This Feat may contain spoilers from the Season of Ghosts Adventure Path
Rare Force Reincarnated Universal Ancestry Source Season of Ghosts (Hardcover) pg. 321
Before your soul returned from death, you interacted with a host of other souls on their way to the
Boneyard. One of these acquaintances owes you a favor. You can temporarily summon it to come to your aid, and it appears as a swirling mass of ectoplasm with indiscernible features and a translucent
dagger, the favored weapon of
Pharasma. This functions as
spiritual guardian that you can cast once per day as a 9th-rank
divine innate spell.
